Dark Magic Attack Question

[Tiger_Paladin]

This is probably a really stupid question to ask, but I just want to get this cleared up:

Dark Magic attack says that you can only activate it when there is a face up Dark Magician on your side of the field.

My question is: Could you then activate it with other Dark Magicians that are not THE Dark Magician such as
Dark Magician Girl
Dark Magician of Chaos
Skilled Dark Magician

The major thing I noticed is that it didn't say, "With the name Dark Magician in it's title", so I figured it was a no but I figured it was better to be safe than sorry.

You must have "Dark Magician" on the field to play Dark Magic Attack. It will not work with any other card.

Figured as much. Thanks.
